Frequently Asked Questions
What international quality certifications do your products hold?
Our manufacturing processes are ISO 9001 certified. All products comply with international standards such as IEC (International Electrotechnical Commission) and CE to ensure global compatibility and safety.
What is the annual production capacity for your equipment?
We operate modern production lines with an annual capacity exceeding 10,000 units. This includes a wide range of oil-immersed and dry-type transformers from 30KVA up to 20MVA.
How is the quality of the RMU and transformers ensured?
We implement a triple-layer quality control system: strict screening of raw materials, monitoring at critical production stages, and rigorous factory testing for every unit before shipment.
Can you provide both copper and aluminum winding options?
Yes, we offer both. Copper windings provide higher conductivity and longer lifespans, while aluminum windings offer a more cost-effective solution for specific project requirements.
What applications are these Ring Main Units suitable for?
They are designed for urban power grids, industrial parks, residential areas, and high-rise buildings, especially where space is limited and high reliability is required.
Is the RMU compatible with SCADA systems?
Absolutely. Our intelligent RMUs feature integrated sensors and communication modules that support seamless data uploading and remote monitoring for grid automation.
